On March 13, 1989, a powerful coronal mass ejection (CME) hit Earth's magnetic field. Ninety seconds later, the Hydro-Québec power grid failed. During the 9 hour blackout that followed, millions of Quebecois found themselves with no light or heat, wondering what was going on? "It was the biggest geomagnetic storm of the Space Age," says Dr. David Boteler, head of the Space Weather Group at Natural Resources Canada. "March 1989 has become the archetypal disturbance for understanding how solar activity can cause blackouts." [imgur]https://imgur.com/QpMEAIP[/imgur] [i][b]Above:[/b] Sunspot 5395, source of the March 1989 solar storms. From "A 21st Century View of the March 1989 Magnetic Storm" by D. Boteler.[/i] It seems hard to believe now, but in 1989 few people realized solar storms could bring down power grids. The warning bells had been ringing for more than a century, though. In Sept. 1859, a similar CME hit Earth's magnetic field--the infamous "Carrington Event"--sparking a storm twice as strong as March 1989. Electrical currents surged through Victorian-era telegraph wires, in some cases causing sparks and setting telegraph offices on fire. These were the same kind of currents that would bring down Hydro-Québec. "The March 1989 blackout was a wake-up call for our industry," says Dr. Emanuel Bernabeu of PJM, a regional utility that coordinates the flow of electricity in 13 US states. "Now we take geomagnetically induced currents (GICs) very seriously." https://www.spaceweather.com/ A lot more info in link ^^^ [/quote] An X4.5 and an M7.3 were what caused it [i]"The first CME cleared a path for the second CME, allowing it to strike with unusual force," says Boteler. "The lights went out in Quebec just minutes after it arrived."[/i] [/quote] The cannibal effect. Or something like that. [/quote] One of those one two punches they worried about during Cycle 24 when we were having all those X-flares. It was amazingly fun to watch but also scary knowing what could happen. [/quote]

I accidentally deleted the OP of this thread during some glitch issues on GLP this morning (10/30/17).
I will be posting some useful links in the next post to make it easier for those posting so you don't have to scroll through a massive OP. :)
I had to delete the first two comments on this thread to do so, but wanted to keep them so I've put them below.
5* and I'm on board.. Simple.. I'm sorry about CH.. He will be missed greatly..
but, the continuation of EQ is an important thing because it's connected to so many things..
Thank you!!! Simple... I will be here.....

I also would like to mention that I know this thread has MANY pages and that it can be somewhat intimidating to join/chime in on a long standing thread as a new member/AC (I've experienced it when I first joined GLP), but we are a VERY welcoming group to those who newly join us. We are a small family of sorts who are all mostly interested in the same earth-related topics (quakes/solar/volcanoes/weather/etc.) and share info on each of those topics as well as 'off-topic' discussions. We genuinely care for one another here and even when we do not agree with each other, we ALWAYS respect each other.
I truly enjoy when new folks join us here. All that I ask is to show respect. :)
